In this example, coupling component 30 forms a part for the barrier at least partially around room 40, and this chamber 40 accommodates second component 20.Described barrier can form a part for the housing in chamber 40.AsFigure 1aIn the cross section of a part of coupling component 30 regardIn figureShown in, coupling component 30 includes the non-conducting material 31 with outer surface 31a, and this outer surface 31a has multiple recess 31b of the coupling element of the array for supporting coupling element 32.Recess 31b is spaced apart around outer surface 31a so that continuous print coupling element 32 is spaced apart by non-conducting material 31.Recess 31b makes the outer surface 32a(of the coupling element 32 being received in recess deviate from the surface in chamber 40) can flush with the outer surface of coupling element 30.Inner peripheral surface 32b(of coupling element 32 faces the surface in chamber 40) can be arranged under inner peripheral surface 31c of coupling component 30.By this way, coupling element 32 is sealed off with chamber 40 by the non-conducting material 31 layers of coupling component 30.
Coupling element or pole piece 32 include permeability magnetic material, such as, and iron-bearing materials or Ferrite Material.In this example, coupling element 32 extends in the axial direction and can have rectangular cross section.In use, coupling element 32 couples from the magnetic flux of first array magnetic field creating elements the 12 to the second array magnetic field creating elements 22 to allow the synchronization of the first and second arrays to rotate against.Synchronizing to rotate against the magnetic gear corresponding to being in coupled configuration, in the configuration, second component 20 is with the speed rotation of n/m times of the speed of the first component 10.
As used herein, phrase " non-conducting material " means material that is the most opaque or electric semi-insulated and that have the relative permeability close to 1, such as, pottery, plastics or composite.Magnetic field creating elements can be any type of permanent-magnet pole, such as, rare-earth magnet.Magnetic field creating elements 12 generally will be set by equal sizes.Similarly, magnetic field creating elements 22 generally will be set by equal sizes.Equally, coupling element 32 generally will be set by equal sizes and to be equally spaced.
Generally, in the use of magnetic coupling piece, first component 10 will be attached to input rotor (such as, described input rotor can be or be attached to pump input driving or the drive shaft of motor), and second component 20 will be attached to output rotor (such as, described output rotor can be or be attached to flywheel or impeller of pump).
In operation, the rotation of input rotor causes the first component 10 to rotate, and the rotation of the first array magnetic field creating elements 12 generates the first shifting magnetic field.When magnetic gear 100 rotating with when rotating to provide the first component 10 of the first shifting magnetic field and to rotate to provide the second component of the second shifting magnetic field to couple via the second array magnetic field creating elements 22, coupling element 32 couples the first and second shifting magnetic fields to maintain the synchronization of the first component 10 and second component 20 to rotate against.If lost, can be by such as existingFigure 3Shown in control arrange, and/or by means of being held to the mouse cage that rotates together with in the first component 10 and second component 20, asFigure 4aArriveFigure 4cShown in, set up or re-establish synchronicity, the two method all will be described below.
In one example, at least one in the first array magnetic field creating elements 12 and the second array magnetic field creating elements 22 includes Halbach array.In Halbach array, magnetic field creating elements is arranged to the magnetic field of the overall gained on a longitudinal side of array and is reinforced compared with the magnetic field on relatively longitudinal side, or much better than, so that make to provide magnetic field on the opposite side of array faint or even zero or close to zero.By at least one array in the first array magnetic field creating elements 12 and the second array magnetic field creating elements 22 by means of being oriented to provide the Halbach array in the magnetic field of strengthening to be provided on another the direction in the first and second array magnetic field creating elements 12,22, between the first and second arrays 12,22, the amount of the flux of coupling can be increased.It is provided as non-Halbach array by means of Halbach array and another array by an array in the first and second array magnetic field creating elements 12,22, the magnetic field crossing over magnetic gear 200 can be " crooked ", so that it is all that the magnetic field intensity in the case of non-Halbach is poor that the magnetic field intensity difference between the first array magnetic field creating elements 12 and the second array magnetic field creating elements 22 is more than at the first and second arrays 12,22.This can have to generate heat vortex flow and magnetic hysteresis and concentrates on the effect on the side of the magnetic gear 200 with Halbach array.Therefore, in this example, the Halbach array that the first array magnetic field creating elements 12 is faced the second array magnetic field creating elements 22 by the magnetic field being oriented to strengthening provides.This flux coupling being possible not only to improve magnetic gear 200 two ends, compared with the situation that the first array magnetic field creating elements 12 is not Halbach array, and also vortex flow and magnetic hysteresis heating can be concentrated on the side of the first component 10, and therefore making it away from chamber 40, heat can be removed more easily in this case.The amount of increase of the flux coupling provided by Halbach array allows the first array magnetic field creating elements 12(to be provided by Halbach array) and coupling component 30 between gap become more wider than in the case of not providing Halbach array, the minimizing of the flux coupling caused because the amount of the increase of the flux coupling produced by Halbach array can offset the increase by the distance between the first array magnetic field creating elements 12 and coupling element 32.Increasing the gap between the first array magnetic field creating elements 12 and coupling component 30 and mean that being acted on the delivery in hot weather life resulted in the region of the first array magnetic field creating elements 12 by vortex flow and magnetic hysteresis can be kept away from coupling component further, this can cause the performance improved.This can also make the removal of heat easy.
?Figure 2aIn show the first example of Halbach array, wherein, the relative orientation of the continuous magnetic pole of described array is rotated by 90 °, asFigure 2aIn indicated by an arrow as.Figure 2bShowing the second example of Halbach array, wherein, the relative orientation of the continuous magnetic pole of described array is rotated by less than 90 °, such as, is rotated by about 45 °, asFigure 2bIn the most indicated by an arrow as.?Figure 2aWithFigure 2bShown in array the magnetic field of enhancing is provided on side A and A' of respective array and faint or substantially zeroed magnetic field is provided on side B and B' of respective array.
If the first array magnetic field creating elements 12 is as Halbach array, it is oriented such that high flux side A or the A' outside facing radially towards the first component, i.e., away from chamber 40, the heat generated by magnetic hysteresis and vortex flow being concentrated on the outside of component 10 and away from chamber 40, this makes heat energy be removed more easily.

In operation, when vehicle traction 208 needs extra power, vehicle traction 208 experiences power demand demand.Controller 202 such as determines power demand demand based on the data of at least one represented in engine efficiency, car speed, the amount of energy that is stored in flywheel, as response, it is determined by whether magnetic gear 100 is synchronized coupling to determine whether flywheel 230 can return to drive system by power.If controller 202 senses magnetic gear 100 and is coupled by synchronization, then controller 202 controls power transmission from flywheel to drive system.If the controller determine that magnetic gear 100 is not coupled by synchronization, this includes determining that magnetic gear 100 keeps decoupling in predetermined time period alternatively, then controller 202 controls operation with coupling or decoupling magnetic gear 100.In order to (again) couples magnetic gear 100, i.e., in order between the first component and second component 10,20, (again) is set up synchronization and rotated against, controller 202 controls pump 210 provides the moment of torsion increased within the limited time period to second component 20, so that the speed being associated with synchronicity that the speed of second component 20 increases above the speed by the first component 10 and gear ratio n/m determines.Then allow second component 20 via the natural dissipation of energy, such as, slowed to the speed being associated with synchronicity by windage, friction or heat loss.Controller 202 then carry out whether magnetic gear 100 coupled by synchronization another determine.If synchronizing coupling to be determined, then controller 202 controls the power transmission from flywheel 230 to drive system, if be not determined, then repeat coupling operation again.
Run duration at vehicle 200, it is understood that there may be must decoupling magnetic gear 100 be favourable situation so that flywheel 230 is departed from the situation of connection or decoupling magnetic gear 100 so that flywheel 230 is departed from connection from car drive 208 from vehicle traction 208.This may in following especially this situation, wherein, vehicle 200 or the part driven by vehicle traction 208 of vehicle, such as, the pneumatic arm of excavator, come static after mobile a period of time.The reduction of the speed of vehicle 200 or its secondary part makes the speed of the first component 10 reduce, and is maintained if synchronizing coupling, then this can cause energy from the indirect loss of flywheel 230.In order to solve this problem, controller 202 is configured to decoupling synchronization and couples from drive system, flywheel 230 is departed from connection, thus the low speed or quiescent period by the secondary part of vehicle preserves the energy being stored in flywheel.
In order to carry out decoupling or " declutching " operation on magnetic gear 100, controller 202 determines the more low dynamics requirement demand from vehicle traction 208, and it includes determining the demand for declutching.Controller 202 is it is then determined that whether magnetic gear 100 is coupled by synchronization.If magnetic gear 100 is coupled by synchronization, then controller 202 controls pump 210 and changes the speed of second component 20 so that second component moves away from the speed being associated with synchronicity.Controller 202 makes pump 208 that the speed of second component 20 is maintained the speed in addition to the speed being associated with synchronicity, until controller 202 determines that the power demand demand of drive system has increased, or until controller 202 is otherwise determined that the demand of clutch gear has stopped.Then controller 202 starts again coupling operation to re-establish synchronization coupling.Such as, make gear depart from couple can by reduce as input rotor flywheel on pull and make the first component 10 slow down come auxiliary energy preserve.This can also contribute to reduce the abrasion on second bearing 70c, 70d.
